Micro Programmable Controller

CPM1A

The CPM1A series micro controllers solve both basic and semi-complex applications. The brick style models include AC inputs/relay outputs, DC inputs/transistor or relay outputs to meet your design requirements. The base I/O for the CPUs ranges from 10, 20, 30, and 40 I/O points with maximum expansion to 100 I/O. Specialized expansion modules include mixed analog I/O, temperature sensor inputs and serial communications

CPM1A J COMPOBUS/S I/O LINK MODULE

The CPM1A controller can function as a Slave to a CompoBus/S Master Module (or SRM1 CompoBus/S Master Control Module) when a CPM1A-SRT21 CompoBus/S I/O Link Module is connected. The CompoBus/S I/O Link Module establishes an I/O link of 8 inputs and 8 outputs between the Master Module and the CPM1A. Up to 3 Expansion I/O Modules or Expansion Modules can be connected to a CPM1A CPU Unit. CompoBus/S Master Module (or SRM1 CompoBus/S Master Control Module)

Functions J CONFIGURATION The CPM1A CPU units feature a compact, one-piece construction that includes 10, 20, 30 or 40 built-in I/O terminals. Three output models are available: Relay outputs, sinking (NPN) transistor output and sourcing (PNP) transistor output.

CPM1A-10CDj-j (10 I/O terminals)

CPM1A-20CDj-j (20 I/O terminals)

CPM1A-30CDj-j (30 I/O terminals)

CPM1A-40CDj-j (40 I/O terminals)

Expansion Up to three Expansion I/O Modules can be connected to a 30-point or 40-point CPU Unit to add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points.

Dedicated I/O Modules Up to 3 Analog I/O Modules or Temperature Sensor Input Modules can be used with 30-point and 40-point CPU Units. Each analog I/O module provides 2 analog inputs and 1 analog output, so a maximum of 6 analog inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O Modules. Each Temperature Sensor Module provides two temperature sensor inputs from either thermocouples or platinum resistance thermometers. Up to 6 inputs can be connected.

J INTERRUPT INPUTS There are two input interrupts in the CPM1A 10-point I/O CPU and four in the 20-, 30-, and 40-point I/O CPUs. Input interrupts are available in two modes.. In addition to normal interrupt inputs, the CPM1A has a counter mode that counts high-speed input signals and triggers interrupts at fixed count multiples.

Application Example: 10 point I/O CPU

20, 30, and 40 point I/O CPU

J INTERVAL TIMER INTERRUPTS The CPM1A has one interval timer. The interval timer shuts down the regular program regardless of the point in the cycle once the time is up, and immediately executes an interrupt processing program. Interval timers are used in the following two modes. Item

One-shot mode

Scheduled interrupt mode

Operation

An interrupt is executed only once when the time is up.

Interrupts are executed repeatedly at fixed periods.

Setting time

0.5 ms to 319,968 ms (0.1-ms units)

Application Example:

Normal program

Computing the Sheet Speed The number of pulse inputs is computed in the interrupt mode at a fixed time to calculate the speed.

J ANALOG SETTING The CPM1A contains two analog setting controls that can be used for a broad range of analog timer and counter settings. Turning the setting control stores values of 0 to 200 (BCD data) in the SR area. Analog setting

Application Example: Analog setting 0 Analog setting 1 *Phillips screwdriver is required.

Tact Operation Control of Conveyor Lines A conveyor can be stopped temporarily as required for assembly processes. When the timer function and limit switches are used in a combination, conveyors can be stopped for a fixed time or can be run at a constant speed for a fixed distance. Fine adjustment of the stopping time can be easily done by using the analog setting controls.
